Jetting I bought loads of jets off eBay some even had a dellorto stamp on them but it was still spluttering so I bought a check size checker I couldn't believe it 155 main jet was bigger than my 160 so now I buy genuine dellorto from here they are a very good price think you get it wrong a top end go's bang (26/01/2016) Paul - Hull

Don’t by cheap eBay jets! I was buying cheap jets of EBay trying to set up my Aprilia RS125. I fitted a Arrow pipe, but kept having set up issues? I called up Luke@pjme for advice, he told me that the cheap jets can vary in size and the Dellorto jets are calibrated, once i had the genuine jets i set the bike up easy.
